Previous Lesson: Three Dimensional Shapes — Week 10
Learning Objectives
- Collect data on sex, birth, and class at home and school.
- Interpret data on a pictogram.
Lesson 1 — Meaning of Data
Data is a collection of facts — numbers, words, measurements, or observations — that can be used for making important decisions.
Example: Before sharing exercise books among pupils in a class, we need to know how many pupils are in that class. Sometimes sharing is based on age, sex, or interest.
Lesson 2 — What is a Pictogram?
A pictogram (also called a pictograph) is a chart that uses pictures or symbols to represent data. Each picture stands for a certain number of items.
Example Pictogram — Favourite Fruits in a Class
| Fruit | Number of Pupils (🍎 = 1 pupil) |
|---|---|
| Apple | 🍎🍎🍎🍎🍎 |
| Mango | 🍎🍎🍎🍎🍎🍎🍎 |
| Banana | 🍎🍎🍎 |
| Orange | 🍎🍎🍎🍎 |
Questions based on the pictogram:
- Which fruit is the most popular? (Mango)
- Which fruit is the least popular? (Banana)
- How many pupils like apple? (5)
- How many pupils altogether? (19)
Lesson 3 — Collecting Data in Class
The teacher guides pupils to collect simple data in class:
- How many boys and how many girls are in the class?
- How many pupils walk to school? How many come by bus?
- What is your favourite colour? (Red, Blue, Yellow, Green)
Pupils then draw a simple pictogram to represent their collected data.
Counting Activity — Numbers 1–250
Count forward: 1, 2, 3 … 250
Count backward: 250, 249, 248 … 1
Skip count in 2s, 5s, and 10s up to 250.
Lesson Evaluation
